Bandsaw Conversion

A few months ago I purchased a band saw off the Chinese equivalent of eBay. What often happens here in China is the factories that make things for western companies sell copies to anyone and his dog! So taking advantage of this I chose the RT-SB 305 U saw that had been made for the German company Einhell AG priced at £180 delivered. I thought I would at least get an average saw that set up correctly would do the simple tasks I needed it for.

Maybe this was my punishment from above but I got a saw that was typically ‘Made in China’ and not what I thought a German company would be selling to anyone! Vibration, very poor cutting and machined like it had been made in the back of a garage. I complained and was sent quite a few parts that were better made but nothing perfect. They repeatedly informed me it had been designed by Germans but as I pointed out it had sadly been made by Chinese!

Anyway after balancing the wheels and making a spacer to bring them inline, buying some Lenox Trimaster blades from the USA, giving the saw a good once over and having a new table CNCed things were better.

After putting up with things for a while I decided the saw needed decent blade guides as the original ones were so badly made. But because you can’t buy such kits here I had to order what I thought would be the answer from Carter in the USA.

When the Jet guides, hex bar and blade guard arrived I could then finish designing a bracket for CNCing to fit the hex bar and top guide, the bottom guide went on easily after a bit of machining. It was all a bit of a pain but well worth it in the end. By the way the CNC work was done for free at a friends factory.

I now have a saw that does everything you throw at it and does it all very well. I know you might think why I didn’t buy a decent saw in the beginning. Well for what I needed a saw for then didn’t justify spending a fortune. Yes I still have spent more than I wanted to but now I have a saw that does the work the way I want it to and much more and still for half the price an equivalent saw would of cost me.

If anyone wants to upgrade such a design of saw I can send you the Solidworks 3D drawing of the bracket along with any info/photo’s that might help. Maybe there is a better way of doing this conversion but I thought I’d share my way.

Hello kaurikid,

Your bandsaw is typical of the workmanship coming from China at the moment, I fact just about all Bandsaws are from this origin if they are in a similar price range.

I bought a bandsaw branded Hafco Woodmaster and have had similar issues with guides etc.

In fact I was so disappointed with it I regretted buying it initially, the table is rough ground and not the normal polished Cast Iron of better “quality” Priced units, and the gauge guides were not the standard size.

I also have an EINHELL drop saw RM 305X and there is a review of it on LJs if you want to take a look.
Its a great saw to use but don’t expect to unpack it and just set to work, I spent quite a few hours getting it to cut perfectly, and once set up, cut perfectly it does.
It appears to me that machinery being produced relies heavily on the user having the mechanical aptitude and tools to be able to get it working perfectly as the suppers cannot or do not want to in the first instant.

No sure how this works with a “do it right the first time” attitude but then we have after many unaccounted hours later from both the supplier and user its corrected.
Its not as though the labour costs at the manufacturer premises is too high.

Go figure

-- Regards Rob

Hi Robert,

You’re quite right but like you say if you don’t have any engineering experience or friends that can help with the machining of parts it can be a real pain. Fitting my new guides wasn’t that bad after having a bracket CNC’d. The original table was made up of 5 interlocking thin alloy pieces and was not flat so I had to do something.

But the top wheel support was unacceptable when I got the saw (photo) as the wheel was so out of line and moving around. If you look at the angle of the wheel axle and the difference in thickness of the sliding lugs both sides. That assembly would have been difficult to replace so I was lucky after complaining that they had a good one to send me.

I have visited many factories here on other business and yes wages are low and qualifications are non-existent along with the ‘I don’t care’ attitude most of them have. So unless they have a stringent quality control in place the end user will suffer.

Most people here buy from ‘’ which is like eBay. I use Google translate and paste it in the taobao search which works well to find things. You will find the price from one seller to another differs tremendously my saw was listed at 1800RMB and anything up to 9000RMB by others!

Thanks for the reply

Hello kaurikid,
I cant believe i found this post. I just picked up a Einhell RT-SB 305U brand new for AU$125 today.
Not impressed with the guides or table at all. As i have a home made CNC capable of milling Aluminium would you mind sharing your files with me?
As you have done all the hard work already (Design) i would appreciate any help.
I dont know if you will see this post, if not after i make 5 posts i will message you.

Hi Denis,

A pleasure to help if I can. What drawings format will you need? I made the original in CoralDraw then had a friend do the solidworks. There are few extra after thought Coral bits that never made it to solidworks that I gave the factory direct. You’re welcome to a copy of everything :-) if I can send the files over LJ’s if not send me your email address.

Best regards,

Any chance you could send plans and details on the replacements to me also?

Have the same model and much the same problems. Aside from the bad table and guide the fence is also utter junk. The handle on it will not even lock it in place properly let alone lock it in place in a parallel fashion. But it was cheap so… What can one expect really.

Problem for me is I do not have access to a CNC as easily but the plans would help.

Where did you get the replacement guides and saw blades?

Hi Hans,

Sorry to hear you’re also having the same problems as I had with my saw. I’ll put together everything I have that might help you improve your saw and send it to you in the next few days.

Regarding the fence you’re right I had the same problems so I made one myself which seems to do the job. I don’t have drawings but I’ll send you enough pictures and info so you’ll have a good idea how I made it.

The guides and hex bar is from

Other problems which I have suffered since and fixed are:

Check the alignment of the top and bottom wheels mine were out by 7mm. I used spacers/shims to correct that.

I replaced the tyres for the blue Carter Products ones.

Replace the bearings in the top and bottom wheels for some quality ones is a good idea, mine wore out quickly.

I order Lenox Trimaster and Diemaster blades from in the USA. Brian is a good contact to make he’s very helpful.

I like to have things more or less right with my machines but this saw was a bad buy after I had found all the problems and fixed them I should of bought a quality saw in the first place. Where did you get your saw from?
Are you in Germany?

We live and learn……..

All the best

Hi Steve,

No not Germany but close to Germany. More specifically Belgium. I ondered it online from a Dutch company. Finding woodworking equipment of any decent brand and quality is far from trivial in the Benelux it seems. As such i often end up buying cheap imitation brands such as Einhell from online web shops instead.

Recently I have decided however that this is just a waste of money so for my latest acquisition, a woodturning lathe, I decided to go with a reputable brand and bought myself a teknatool DVRxp. I had to drive 300 kilometers to get it but it was worth it.

I am now examining all my options for my existing machines (many of which suffer from similar issues and limitations), either modify them to be ‘better’ or just replace them outright. This lead me here to your post.

For any new or budding woodworkers out there. Trust me when I say you should not invest in any cheap imitation machines. Do your research first and save up for a decent model. This does not necessarily mean the most expensive machine out there but it usually does mean to ignore the cheap ones. Online forums and reviews are your friends here.
