I inherited this power scraper which I believe to be a Renz, along with a bunch of other scraping stuff from a friend who passed away a couple of years ago. I didn't know he had it, I wish I had known and asked him to show me how to use it.
I've never done much with a power scraper, some roughing a few times but that's it. I had a really nice Biax at the time I got this one but I almost never used it and have since sold it because I don't need two of them. I kept this one for sentimental reasons, although it's not in great shape, I think it will fit my needs.
Recently I took it out and decided to give it a try. It is variable speed so after some roughing, which went really quickly, I slowed it down for finishing. I have been practicing on a small surface plate, and got it down to just under 20ppi with about 30% contact. I think to get it any better I'll need to shorten the stroke a bit which is about 5/16" right now.
There is a square head rod inside a hole on the front of the scraper. It says + on one side and - on the other but turning this rod only turns the motor and makes the tool reciprocate, it does not change the stroke.
What am I missing here. I know these are pretty rare but I hope someone out there is familiar with this model. Rich, I know you've said you've used Renz scrapers in the past and are not crazy about them, but it's what I got. Any other input is appreciated as well. Thanks.
