Consew 206Rb-1

[Jovial]

Hey everyone,

A few months ago I picked up a Consew 206RB-1 with a 3/4hp 550watt servo motor. I have been using it fairly constantly and while the stitches seemed to be ok quality wise they just were not up to what I wanted out of the machine. One of the reasons is that on higher speeds (where the torque was present) I couldn't control the thing. The other problem I had was on slow speeds (where torque was lacking) I just couldn't pierce the leather properly, or without a helping hand wheel turn. Tonight while doing routine maintenance I decided to check for other sized pulley wheels in my grandfather's garage. Luckily for me I found a 1" pulley wheel and slapped it on there. This was exciting to me because earlier I had read through Wizcraft's sticky and that change gave me the 3:1 reduction he mentioned.

To my dismay though, I found that my belt was now too long no matter how I changed the motors mounted height. So I ran out and picked up a new belt and a metric tap & die set ( to try to fix the threads on the reverse/stitch length lever). Well after that the belt worked and the machine is stitching again more beautifully than ever! The tap & die set however was a total bust because it was lacking the M7 - 0.90 die that (thanks to the included gauge) I found to be needed.

At any rate I finally have the control and stitch quality that I have been after and I decided to throw some pictures up to see if anyone else considers the stitching satisfactory. If anyone felt like throwing out an opinion on them I would greatly appreciate it.

The pictures show stitches through double and quadruple layers of 4 oz veg tan. (All on the same piece of scrap)

Are you using a chilse point needle? Just cureious as there seems to be a lot of material moving on the backside. Front stitches look beautiful...

You need to change to a twisted chisel point leather needle. The bottom is not right. Look for series 135x16 needles. Those are t angled, chisel point.

The ones I have are marked 135x16TRI. What would the twisted chisels be marked Wiz?

Thanks for the feedback hunt. Ill check it out then and see if anything has been moving as I stitch.

My leather point needles are marked 135x16 NW

Thanks! Now when I stop by the store to get them I can be sure they give me the right thing

Allright I stopped by the my sewing machine mechanic's place and have the 135x16 NW needles on order. I took him my needle plate and feed dog to check out because they looked a little worn to me. He informed me they were shot and probably not worth using, so I also have those on order! Hopefully I'll get this thing running better really soon. Once I have the time and money to have him go over it I figure he can give it a good tune up and check the timings etc. for me. Just figured I'd give an update. Once I have everything I'll put up some new pictures to see if it looks better to you.

Hi,

Your 135x16TRI needles should work just fine. They are what most folks use now. You may be able to get by with a smaller needle size if you want. You can also close up the stitch holes with some form of slicker to get a nicer look.
