Replacement motor for Preac saw

Recommended Posts

With the new upgrade on the Preac, will it be able to cut 1/8 thick brass?  Am looking for a good saw for cutting copper and brass and the upgrade may be just what am looking for.  I know, you ask why not just use a jeweler's saw. Its a little slow and am not getting any younger.  Thanks. Gary

Gary i never ordered the motor as i got my old motor fixed, I have a Jim Byrnes and a Proxxon table saw, so i have a bit of  over kill in the table saw area. I actually use the Dremel with a cutting wheel, to cut brass as although i have the blades to cut metal for many of my other saws  it just so easy to use the Dremel. I also have a blade for the Proxxon band saw, but it takes 10 minutes to set it up and 30 seconds to use Dremel. I suppose if i had alot of cutting i would set up one of my other saws.

 

i use the Jim Byrnes for my regular wood working task, the Preac as my fine delicate woodworking saw, Proxxon as my saw for heavy work.

Hi Kevin. Like you said it takes a lot longer to set the band saw up and about 30 seconds to cut the material. What I want to do is set up a small band saw as a dedicated saw for cutting metal copper, brass and others down to workable sizes, when it is a little on the thick side, so I don't have to spend ten minutes changing the tool over to do a 30 second cut.  I also think doing this will keep the cut metal more square for working.  The motor on the Preac runs, its just really under powered and has a hard time cutting anything. Figure that the upgrade will at least make it able to cut 3/32  thick materal and will be a dedicated saw for doing grating. My Byrnes saw is the real work horse and  cut's most of the ship wood with the  inca and Grizzly cutting down the larger pieces for the Byrnes .  Gary

I am sure what you are proposing will work fine. I have been using my Proxxon chop saw when i have lots of repeated  cuts to do. With the Naparima i will have 44 post to cut and will use this saw to make the cuts. However it would not be useful for making cuts on large pieces of brass material. 
multiple saws are a wonderful luxury when you have multiple set up to make.

Pardon my ignorance, but I always wondered what was meant by a 'Chop Saw' is. Now I've seen this photo, it's inspired me to design and make a useful mini table top version, using a natty mini drill just arrived. We aren't always cutting lumber.

As for replacement motors in general, it may be a good idea to look into the high-torque motors for electro-scooters. Their arrival on the market means that spare motors are now cheap and easy to come by. There seem to be 12V, 24V, 36V and 48V brushed versions available on the wellknown on-line market places. High torque means chunky motors, so you will have to see, whether it fits into your existing equipment.

Fleabay:- 120W scooter motors going for around £18. Several Unimat owners have converted to these. A bit of a faf to fit but possible. Hell a lot cheaper than the ones previously available.

The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.

The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal.
