Question: Is the adjustment hub on this piece plastic? That seems to be the biggest complaint with the HF version which may just be a knock off of this unit.
Document: I was trying to decide between this model and the cheaper lookalike version sold at HF and such. The biggest benefit is the all metal construction. The cheaper models have a plastic hub which is prone to failure. If you want a ring roller, even for a weekend user like myself, get this piece.
Great well made roller. Real metal cohstruction, not that cheap plastic like the HF cheapo that breaks after the first use.
This ring roller will leave ridges on round bar and checker board pasterns on flat bar. If you are not concerned with the finish of the piece after using this roller then I would consider this product to work fare.
This is the all-metal machine I should have started with, rather than waste my money on the H-F tool made with plastic parts.It is a strong, solid, well built tool, and the better handle makes it easier to use.
This ring roller works really well. Remember, it's manual so you need to bring your stamina and muscles to the table if you are making a lot of circles in 1/4" round bar. I've done flat steel and 1/4" square bar also. This little machine rocks. It's not precision but gets the DIY projects done. I've made candle holders, lamps, wine racks, wall art and many more projects with this ring roller and it's still working great.
This is a solid roller which works great for rolling things like 1/4&#34; rod or small flat stock. I've made a number of things with it within the first week of getting it and for the price I've very happy with the quality and construction.It's a great addition to the shop and has all kinds of uses.
My mistake, I was focused on a different product. This ring roller is excellent. Rolls rings from tubing, no problem!
